You need to get him to an avian vet. I've experienced something like this once & it was from my cockatiel that had flown into the wall & was concussed. She was in so much pain with it.
I'm not saying it's the same thing but It's not normal behaviour. Where are you? You need to find an avian vet. Sorry to be dramatic but we need to be.
Also stop putting anything in the water, make sure he has fresh clean water for the time being.
How long has he been like this? Keeps us updated
